G.R.S. Mead 
Thrice-Greatest Hermes 
Studies in Hellenistic Theosophy and Gnosis (3 books in One ) Volumes I-II-III (Annotated)

Complete edition, fully annotated (3 280 footnotes), easy-to-read layout.

G.R.S. Mead was a noted and influential member of the Theosophical Society. He studied the Hermetic and Gnostic religions of Late Antiquity. Mead’s huge book-Thrice-Greatest Hermes-is a classic work on the philosophical Hermetica and the figure of Hermes Trismegistus. This complete edition compiles the three volumes in one book. The first volume (Prolegomena) gives an extensive study of the Hermetic corpus and the origins of Hermeticism. The second volume (Sermons) gives a translation of the entire Corpus Hermeticum and the Asclepius, with extensive commentary following each section. The third volume (Excerpts and Fragments) gives the excerpts and fragments that make up the rest of the Hermetica, namely from Stobaeus, but also from the Fathers (Clement of Alexandria, Tertullian, Augustine, etc.) and the philosophers of antiquity (Zosimus, Jamblichus, Fulgentius, etc.)

This work offers substantial quotes from a wealth of sources (edition fully annotated with 3 280 footnotes). This book is well worth reading for all those who wish to study the Corpus Hermeticum in its entirety.
